Phoenix - redirects in router file

The redirect library addresses this shortcoming by providing with a redirect/3 macro, allowing to redirect a request from one path to another in the router.exfile:

redirect "/", "/users", :permanent # 301 redirect
redirect "/", "/users", :temporary # 302 redirect

We ran into this on the project I’m working on. We found this blog post to be a pretty good way to do this: How to Redirect from the Phoenix Router | Viget

We ended up with a plug that lets us do this:

get "/", Redirect, to: "/datasets"

You can see our implementation here: smartcitiesdata/apps/andi/lib/andi_web/plugs/redirect.ex at master · UrbanOS-Public/smartcitiesdata · GitHub

It looks like there is a plug_redirect package in Hex that does adds a redirect keyword. Their Readme suggests using it as its own Plug in your endpoint, but at a quick glance I don’t see any reason you couldn’t use it in a Phoenix router

One command that i find very useful when dealing with routes is mix phx.routes it shows you what routes you have.

Also have a look at this Controllers — Phoenix v1.8.8 it should show you how to redirect with different options.

Hope that it helps

Phoenix.Controller.redirect/2 is a plug, and the generated router for phoenix has it imported by default. Together with forward you should be able to use it already without the need for additional code.

I think this is a good idea, if a little niche. although you’d want to implement it as redirect "/", "/users" because redirect "/", UserController, :list is ambiguous. Multiple paths can route to the same controller action.
